TOBACCO-PIPE.

Specification of Letters Patent. Patented Mal. 26, 1912.

Application filed September 26, 1910. Serial No. 583,973.

. To all whom 'it may concern:

Be it known that I, JOHN BACHMANN, a citizen of the United States, residing at Chicago, in t-he county of Cook and State of Illinois, have invented certain new and use.

ful Improvements in Tobacco-Pipes, of

`which the following is a description.

My invention belongs to that general class of devices known as tobacco pipes, and relates particularly to a straight or bent stem pipe, having an even or continuous unobstructed passage' through the pipe from thc mouth piece to the exterior ofthe bowl, and provided with a closure for normally closing the end of the passage at the exterior of the bowl when the pipe is in use.

My invention has among its objects the production of a simple, convenient, efficient and satisfactory pipe of the kind described that may be easily and perfectly cleaned.

To this end my invention consists in the novel construction, arrangement Vand combination of parts herein shown and described, and more particularly pointed out' in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts, Figure 1 is a side elevation of. a straight stem pipe with a cleaner therein.

Fig. 2 is a longitudinal sectional view of the same, the cleaner removed. Fig. 3 is a similar longitudinal sectional view of the curved stem pipe. Fig. 4 is a plan view of the preferred form of closure. Fig. 5 is a sectional view of the same, and Fig. 6 is a perspective view of the closure removed from the pipe.

Referring to the drawings, 1 represents the bowl of the pipe provided with a stem 2 and mouth piece 3, which stemand mouth piece may be formed integral or separate, as shown in the drawings. The bowl l is provided with the usual tobacco chamber of any desired shape. Extending through the pipe stem and bowl from end to end is an even or continued passage a, which is preferably so arranged that it includes the lower p0rtion of the chamber in the bowl. The passage froni the stem to the chamber is always open when the pipe is in use, the end of the passage at the exterior of the bowl be'- ing preferably normally closed by a plug or closure of any suitable material, which may be retained inposition in any desired way. As shown, the plug b is preferably rotatable and arranged with its axis of rotation inclined, or at an angle to the passage a. The closure or plug b is provided with an opening al therethrough, which is also inclined or at an angle to the axis of rotation of the plug, so that when the plug is inV position substantially as shown in Figs. 2 to 5 inclusive, the passage a and al is continuous and open throughout the length of the pipe, sothat a suitable cleaner may be inserted and kpulled back and forth, thoroughly cleaning the pipe throughout the length of the passage, and at the same time cleaning the bottom G of the bowl.

` When the closure is turned part way around, the duct or passageway a1 in the closure is substantially as indicated by the dot-ted lines in Fig. 5, closing the passageway a as shown. The plug is provided with a slot in the same so that it may be turned with the finger nail, a knife blade, a coin, or the equivalent. The plug b may be `maintained in position in any desired way,

as shown it is preferably locked on the pipe by a cup-shaped part e of suitable material, preferably metal, which is outwardly flanged at the exterior of the pipe and then inwardly flanged over the end of the plug b,

thereby maintaining or locking the same in the cup so that it is never necessary to remove the plug from the pipe to cleanthe same. The inwardly flanged portion of the cup e engages the plug with sufficient friction to prevent any accidental turning thereto but to readily permit the same to be turned whenever desired by the insertion of aA tool or the finger nail in the slot formed in the plug for this purpose. The cupshaped part-s c are retained in position on the pipe yin any desired way, small nails or brads being shown for the purpose. It will be noted that with this construction the plug or closure cannot become lost or injured, being always protected and retained in position; that there are no threads to wear, nor can the plug drop out while the pipe is being used.

WhereA the pipe stem is made up of two parts 2 and 3, as shown in the drawings, I

provide t-he usual connectingpiec'efor cou` pling D, which, however, is fitted tightly to both pieces so that there is no open space for the juice or nicotin to settle in. By being closely fitted, the passages in the stem and mouth piece are always in alinement,VV so that there is no shoulder or obstruction to interfere with the pipe cleaner. Inasmuch as the passage is continuous throughout the pipe stem, it is never necessary to remove the stem 3, or mouth piece, as is the case with the ordinary pipe when cleaning the same. lith the ordinary pipe, when the pipe cleaner is pushed in the stem toward the bowl and drawn back, if the mouth piece 3 has not been removed the nicotin or tobacco juice is drawn into the mouth piece. The only way to avoid this is to remove the stem and pass the cleaner through from the mouth end. However, in continually cleaning the pipe, the threads in one of the parts will sooner or later become worn so that the removable stem does not fit tightly and nicotin will gather at one or the other, or both ends of the plug D.

Tith my pipe cleaner there is no necessity for removing the mouth piece 3, as the cleaner can be worked back and forth and finally drawn through the passage al out through the plug It will be particularly noted that with my pipe the passage a need not be increased in size over the passages in the pipes in use, and the only metal that the smoke or nicoltin can come in contact with when the closure ZJ is closed is an area equal to the area of the passageway, which is comparatively small. The plug Z) can be fitted to old pipes in use, or to new pipes during the manufacture, but in the first instance, however, if there is not a tight fit at the plug or coupling D, it should be corrected.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same within the scope of the appended claims, hence I do not wish to be understood as limiting myself to the exact construction, arrangement or combination of parts herein shown and described.

That I claim as new and desire to secure by Letters Patent is l. A tobacco pipe comprising achambered bowl, and a stem provided with a continuous unbroken passage therethrough to the exterior of the bowl, and including a portion of the chamber in said bowl, and means normally closing the end of the passage at the exterior of the bowl comprising a closure rotatably mounted in said bowl and adapted to normally overlie and close the end of said passage, said closure being provided with an eccentrically disposed port extending therethrough adapted upon rotation of said closure to be brought into registration with said passage to form a continuation thereof.

2. A tobacco pipe comprising a chambered bowl and a stem provided with a continuous passage therethrough to the exterior of the bowl, and including a portion of the chamber in said bowl, said passage being `of substantially uniform diameter throughout its length, and a movable element for the end of said passage permanently secured to said bowl and normally closing the end Aof the passage, said closure being provided with a port extending therethrough of substantially the same diameter as said passage and adapted to aline therewith in one position of the closure to form a continuation thereof whereby there is provided a continuous passage of substantially uniform diameter for a cleaner through the stem, bowl and closure.

3. A tobacco pipe comprising a chambered bowll and a stem provided with a continuous passage therethrough to the exterior of the bowl, and including a portion of the chamber in said bowl, said passage being of substantially uniform diameter throughout its length, said bowl being provided with a circular' recess in the exterior thereof, a closure rotatably mounted in said recess and fitting snugly against the bottom thereof, said closure being provided with a port extending therethrough adapted to register with the passage in the pipe, and means for permanently securing said closure in position and arranged to frictionally hold the same against rotation. 4. A tobacco pipe comprising a chambered bowl and stem provided with a continuous passage therethrough to the exterior of the bowl, and including a portion of the chamber in said bowl, said bowl being provided with a circular recess in the exterior thereof, a closure rotatably mounted in said recess and provided with a port extending therethrough adapted to register with the passage in t-he pipe, and a circular metallic flange secured to the exterior of said bowl and overlying the outer surface of said closure.
